Abstract
A method for detecting errors in a processing device is disclosed. A data source unit of a processing device transmits data and a qualifier synchronously with the data, the qualifier to indicate the data is uncorrectable. At least one intermediate functional unit in the processing device receives the data and the qualifier. The at least one intermediate functional unit detects the data is uncorrectable based on the qualifier. The at least one intermediate functional unit transmits, without using, the data and the qualifier synchronously with the data to a data consumer unit of the processing device. The data consumer unit receives the data and the qualifier. The data consumer unit detects the data is uncorrectable based on the qualifier. The data consumer unit maintains, without using the data and the qualifier.
